Option to run scripts with npm's --silent flag

[marklawlor]

Describe the feature you'd like to request

Current output:

my-project:test:
my-project:test: > my-project@0.0.0 test
my-project:test: > echo 'hello-world'
my-project:test:
my-project:test: hello world

Output I'd like

my-project:test: hello world

Describe the solution you'd like

npm run has a --silent option that removes the extra lines added by npm when running a script. I would like an option in turbo.json to pass this flag to npm run.

Describe alternatives you've considered

Have an environment variable NPM_OPTIONS to pass extra command line flags to npm (similar to NODE_OPTIONS for node), or an npm-options attribute in turbo.json

_Update: Using bare double-dash for this no longer works since #1405 (v1.3.0 release), which changes the behaviour to pass arguments after the double-dash through to the command run by npm in each workspace rather than npm itself - probably the more useful behaviour in any case. Alternative method using npm_config_loglevel posted in new comment below._

~~Appears to achieve the desired effect by passing --silent after a bare double-dash (thus passing the --silent flag through to the npm run command rather than interpreting as a flag for turbo) -~~

turbo run test -- --silent

Agree it would be pleasing to have this feature natively in Turborepo config to avoid the need for shell jitsu.

Turns out npm supports passing config via environment variables using the npm_config_ prefix, so e.g. this does the trick:

npm_config_loglevel=silent turbo run test

Has anybody found a solution that works for pnpm?

[PacoSoftwerft]

As I sometimes run turbo via npm it may be helpful to know you can chain the double dash. Example:

npm run xy -- -- --flag

What happens npm run xy -- -- --flag -> turbo run xy -- --flag -> xy --flag

For pnpm add

reporter=silent

to your .npmrc (https://pnpm.io/npmrc).

This setting is undocumented, but it's equivalent to --silent: https://github.com/pnpm/pnpm/blob/main/pnpm/src/shorthands.ts#L8

Unfortunately this silences all pnpm commands (including pnpm i).
